The invention relates to a water-permeable breakwater structure. The structure comprises a frame and wall piles. The water-permeable breakwater structure is characterized in that the frame is divided into upper and lower layers; the upper and lower layers are connected through stand columns; each frame layer comprises two guide beams; the guide beams are connected through straining beams; wall pile guide grooves are formed in the guide beams, and the wall piles penetrate inside the wall pile guide grooves; and a retaining wall is arranged on the side, close to the sea, of the guide beams, and retaining wall holes are formed in the retaining wall.Compared with the prior art, the structure has the beneficial effects that the water-permeable breakwater is permeable, and water body exchange can be realized. The water-permeable breakwater structure has a gravity, high-piled plate type structure, has a stable structure and high bearing capacity, and can be used for effectively resisting wave brushing; the construction efficiency of breakwater can be greatly improved since the frame and the wall piles are onshore prefabricated; and the retaining wall is arranged on the side, close to the sea, of the guide beams to retain wave loading, and retaining wall holes are formed in the retaining wall to exchange water inside and outside the breakwater.
